The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0034] As Figures 1 to 9 shown, this embodiment provides a radio frequency test socket, which includes a housing assembly 1, a fixing assembly 2, and an elastic assembly 3. Among them, the housing assembly 1 has a test hole 11, an assembly cavity 12, and a first limiting structure 13; the fixing assembly 2 has a fixing terminal 21, a second limiting structure 22, and a third limiting structure 23; the elastic assembly 3 has an elastic terminal 31 and a fourth limiting structure 32. By using the radio frequency test socket of the present utility model, in the insertion direction of the test probe, through the limiting cooperation between the second limiting structure 22 and the first limiting structure 13, the housing assembly 1 and the fixing assembly 2 can play a limiting role, thereby ensuring the accuracy of the position of the fixing assembly 2 after assembly; at the same time, the fourth limiting structure 32 and the third limiting structure 23 are in limiting cooperation in the insertion direction of the test probe, so that the elastic assembly 3 and the fixing assembly 2 can play a limiting role, thereby ensuring the accuracy of the position of the elastic assembly 3 after assembly, and further reducing the mismeasurement rate during user application. By using the radio frequency test socket of the present utility model, it is possible to ensure the accuracy of the positions of the housing assembly 1, the fixing assembly 2, and the elastic assembly 3 after assembly, effectively solving the problems of poor accuracy of the radio frequency test socket in the prior art, which easily leads to the failure of the internal switch function and mismeasurement during application, and achieving the purposes of miniaturization, high assembly consistency, and simple assembly process.

[0035] In this embodiment, as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the first limiting structure 13 includes a first limiting inclined surface 131 and a second limiting inclined surface 132, and the second limiting structure 22 includes a third limiting inclined surface 221 and a fourth limiting inclined surface 222. The first limiting inclined surface 131 and the third limiting inclined surface 221 are abutted in the insertion direction of the test probe, and the second limiting inclined surface 132 and the fourth limiting inclined surface 222 are abutted in the insertion direction of the test probe. In this way, the housing assembly 1 and the fixing assembly 2 can be limited in the insertion direction of the test probe, so as to ensure the accuracy of the position of the fixing assembly 2 during assembly; at the same time, such a setting can also play a guiding role during assembly and facilitate installation.

[0036] Further, as Figures 5 to 7 shown, the third limiting structure 23 includes a fifth limiting inclined surface 231 and a sixth limiting inclined surface 232, and the fourth limiting structure 32 includes a seventh limiting inclined surface 321 and an eighth limiting inclined surface 322. The fifth limiting inclined surface 231 and the seventh limiting inclined surface 321 are abutted in the insertion direction of the test probe, and the sixth limiting inclined surface 232 and the eighth limiting inclined surface 322 are abutted in the insertion direction of the test probe. With such a setting, the fixing assembly 2 and the elastic assembly 3 can be limited in the insertion direction of the test probe, so as to ensure the accuracy of the position of the elastic assembly 3 during assembly; at the same time, such a setting can also play a guiding role during assembly and facilitate installation.

[0037] Alternatively, in some embodiments not shown in the figure, one of the first limiting structure 13 and the second limiting structure 22 has a limiting protrusion, and the other has a limiting groove, which can also play a limiting role and ensure the accuracy of the position of the fixing assembly 2 during assembly; similarly, one of the second limiting structure 22 and the third limiting structure 23 has a limiting protrusion, and the other has a limiting groove, which can also ensure the accuracy of the position of the elastic assembly 3 during assembly.

[0038] Specifically, the housing assembly 1 includes a housing main body 14 and a housing mounting member 15. Among them, the housing main body 14 includes a cylindrical section 141 and a bent section 142 that are connected to each other. In this embodiment, the bent section 142 is bendably arranged, so that the housing mounting member 15, the fixing assembly 2, and the elastic assembly 3 located in the assembly cavity 12 can be fixed; and the housing mounting member 15 includes a cylindrical member 151 and a first limiting block 152 and a second limiting block 153 connected to the cylindrical member 151. With such a setting, the cylindrical member 151 is inserted into the cylindrical section 141, and the first limiting block 152 and the second limiting block 153 are connected to the bent section 142. Among them, one end of the bent section 142 has a connecting protrusion, and the side of the first limiting block 152 facing the bent section 142 has a limiting groove, and the connecting protrusion is located in the limiting groove. Among them, the cylindrical member 151 has a test hole 11, and the side of the first limiting block 152 facing away from the bent section 142 has a first limiting structure 13.

[0039] Optionally, the cylindrical section 141 has a through hole, and the cylindrical member 151 is inserted into the through hole.

[0040] In this embodiment, the housing main body 14 and the housing mounting member 15 are an integrally injection-molded structure. This arrangement can avoid the assembly between the housing main body 14 and the housing mounting member 15, thereby improving the assembly accuracy of the RF test socket.

[0041] Optionally, the housing main body 14 is made of a metal material, and the housing mounting member 15 is made of an engineering plastic material.

[0042] As Figure 1 , Figure 5 and Figure 6 shown, in this embodiment, the fixing assembly 2 includes a fixing base 24. Among them, the fixing base 24 includes a connecting block 241 and third and fourth limiting blocks 242 and 243 connected to both ends of the connecting block 241. One end of the fixing terminal 21 is passed through the connecting block 241 and connected to the connecting block 241, so that the fixing terminal 21 can be fixed to ensure the stability during connection; in this solution, on one side of the third limiting block 242 and on one side of the fourth limiting block 243, there is a second limiting structure 22, and on the other side of the third limiting block 242 and on the other side of the fourth limiting block 243, there is a third limiting structure 23. This arrangement makes the volume of the fixing base 24 smaller and the structure more compact.

[0043] In this embodiment, the fixing terminal 21 and the fixing base 24 are an integrally injection-molded structure. Similarly, this arrangement can avoid the assembly between the fixing terminal 21 and the fixing base 24, thereby improving the assembly accuracy of the RF test socket.

[0044] Optionally, the fixing base 24 is made of an engineering plastic material, and the fixing terminal 21 is made of a metal material.

[0045] Specifically, as Figure 1 and Figure 7 shown, the elastic assembly 3 includes an elastic seat 36. Among them, the elastic seat 36 includes a fifth limiting block 33, a support block 34, and a sixth limiting block 35 connected in sequence. The elastic terminal 31 is connected to the fifth limiting block 33, the support block 34, and the sixth limiting block 35, so that one end of the elastic terminal 31 can be fixed; and both the fifth limiting block 33 and the sixth limiting block 35 have a fourth limiting structure 32, which further improves the convenience of assembly between the elastic assembly 3 and the fixing assembly 2.

[0046] Optionally, the elastic terminal 31 is made of a metal material, and the elastic seat 36 is made of an engineering plastic material.

[0047] Among them, the support block 34 has a ramp step 341. When the test probe is inserted and contacts the elastic terminal 31, the ramp step 341 is provided to support the deformed elastic terminal 31.

[0048] Similarly, the elastic seat 36 and the elastic terminal 31 are set as an integrally injection-molded structure. This avoids the assembly between the elastic seat 36 and the elastic terminal 31, thereby improving the assembly accuracy of the RF test socket.

[0049] Specifically, the elastic terminal 31 has a plurality of contact elastic pieces 311, and the plurality of contact elastic pieces 311 can all abut against the test probe. With such a setting, the stability of the contact between the test probe and the elastic terminal 31 is ensured.

[0050] As Figure 8 shown, after the test probe is inserted into the test hole 11, the test probe abuts against the elastic terminal 31.

[0051] As Figure 9 shown, the elastic seat 36 can limit the elastic terminal 31 in the extending direction of the elastic terminal 31, and the housing mounting member 15 can limit the elastic terminal 31 in the height direction, thereby ensuring the stability of the elastic terminal 31 during operation; similarly, the fixing seat 24 can limit the fixed terminal 21 in the extending direction of the fixed terminal 21, and the housing mounting member 15 can limit the fixed terminal 21 in the height direction, thereby ensuring the stability of the fixed terminal 21 during operation.

[0052] The advantages of the RF test socket of the present utility model are as follows:

[0053] 1. The shell assembly, the fixing assembly and the elastic assembly that form the finished product are combined with each other in pairs with inclined planes. The inclined plane matching facilitates assembly and at the same time plays a role of mutual limitation to each other, ensuring the accuracy of the assembly position and reducing the mismeasurement rate during user application; at the same time, it effectively prevents the solder paste or flux from climbing into the product interior during chip mounting, resulting in the failure of the switch function.

[0054] 2. The elastic terminal adopts multi-contact contact, ensuring contact stability; and a ramp step is designed to support the contact elastic piece of the elastic terminal when the test probe is inserted.

[0055] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
